Low Peel Bridge. Ashiesteel Bridge, sometimes called Low Peel Bridge, crossing the River Tweed, was built in 1847. Constructed of whinstone rubble, its span is 132 ft, while it measures 203 ft in length, including the approaches, by 18 ft 10 ins in overall breadth. The structure was repaired in 1952. It is understood that the bridge collapsed once during its original construction, before the arch was completed.

This road bridge crosses the Tweed in a single graceful semi-elliptical arch of 13112 ft with a rise of 26 ft. It is one of the world’s largest rubble masonry spans and the closing bridge achievement of J. & T. Smith of Darnick.
The present structure, dating from 1847–48, represents the second attempt to build this bridge. It was reported
that when the temporary timber centring supporting the arch of the first bridge during its construction was
removed ‘the keystone shot up into the air and the whole bridge collapsed’. The bridge was rebuilt at the Smith
brothers’ expense, but the original contract price of £1200 proved insufficient to meet the cost of both bridges and they ‘failed in business’. The use of a semi-elliptical arch, in addition to maximising the waterway, is perhaps indicative of their understanding that this shape being flatter at Ashestiel Bridge the crown was less likely to fail through the crown being forced upwards. A reinforced concrete slab, spanning over two external
and two internal spandrel walls, was cast in the early 1950s, the bridge remaining open while this work was
done. The parapets and spandrel faces were taken down and rebuilt in the early 1980s.
